AXLE-JOURNAL.

SPECIEZCATION forming part of Letters Patent No. 684,683, dated October15, 1901.

Application filed January 22, 1901. Serial No. 44,290. (No model.)

To all whom, it may concern.-

Be it known that I, CHRISTIAN Fox, a citizen of the United States, and aresident of Gap, in the county of Lancaster and State of Pennsylvania,have invented new and useful Improvements in Axle-Journals, of which thefollowing is a full, clear, and exact description.

This invention relates to means for mounting wheels upon axle-journalsso that the movement of the wheels will be attended by the leastpossible friction and so also that should the nut become disengaged fromthe journal the wheel will still be held in place.

The invention further embodies peculiarities of construction renderingthe bearing entirely dust-proof and permittingit to be oiled withoutremoving the wheel.

This specification is a specific description of one form of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side view of the invention. Fig. 2 is a longitudinalsection thereof. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4is a section on the line 4 t of Fig. 2, and Fig.6 is an end elevation ofthe annulus at the inner end of the hub.

or represents the axle spindle or journal, and 1) represents the box,which is adapted to be fixedly engaged in the hub of the wheel, asusual. The box I) is mounted on the spindle through the medium ofbearing-balls c and at, so that these balls sustain the box out ofcontact with the spindle and permit the rotation of the box with verylittle friction incident thereto.

The parts a and h are formed with opposing surfaces at and 6, betweenwhich the balls 0 bear, and these balls are held in place on the spindleby a ring e, which is sprung around the spindle in the position shownand which may be removed to permit the emplacement and displacement ofthe balls when desired. The outer end of the box I) is provided with aconcave surface 19*, forming a ball race, in whichare engaged the ballsat. These balls are held in a cupf, which is threaded on the end of thespindle and provided with a ring 9, sprung into position and serving tohold the balls 61 in place and also to exclude dust from the hearing.The balls at travel between the race I) and a correspondingly-arrangedsurface on the cup f, forming a race thereon.

The cup f is threaded on the end of the spindle, as shown, and againstthe outer face of the cup bears a washer h, having a tongue h, whichfits in a longitudinally formed groove a in the end of the spindle ct.This prevents the washer from turning on the spindle. The washer is notthreaded, but simply fits loosely over the spindle end. A cap-nutt'screws on the end of the spindle and bears against the washer h, forcingit firmly against the cup f. It will be observed that since the washerhis not permitted to turn the turning movement of the cap-nut 2' willnot be imparted to the cup f, and consequently when the cup is properlyadjusted on the spindle and the washer h in place it will be impossibleto disturb the adjustment of the cupfby turning the not i. This enablesthe nut to be screwed up in the tightest possible manner against the capwithout disturbing the nicety of adjustment of the beariug-balls.

At the inner end of the spindle a an annular rib a is formed, and theinner side of this rib is formed with an annular groove 0. Over the riba fits an annulus 70, which has an annular tongue 76 fitting loosely inthe groove a and the annulus is screwed firmly over the inner end of thebox b. The annulus therefore is carried by the box and turns with thesame, the interengaging parts 70' and a forming an absolutely dust-proofconnection. Formed in the box 1) is an oilopening 12 which is covered bythe annulus 70 when the latter is in place. By screwing the annulus kpartly back toward the disen gaged position of the annulus theoil-opening b will be exposed and the bearing may be oiled withoutremoving the wheel from the spindle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of an axle-spindle hav ing anannular rib at its inner portion, a box mounted thereon, a bearing-cupthreaded on the end of the spindle and forming a bearing for the end ofthe box, balls bearing between the box and cups, a Washer fitted on thespindle and engaging the outer face of the cup, the washer beingincapable of turning on the spindle, a nut screwed onthe end of thespindle and bearing against the Washer to hold the bearing-cup in place,and an annulus secured to the inner end of the boX and engaging over therib of the spindle.

2. The combination of an axle-spindle having an annular rib at its innerend, the rib being provided at its inner face with an annular groove, abox mounted to turn on the spindle,

bearing devices arranged at the outer end of the box, and an annuluscarried by the inner end of the box and embracing the rib of thespindle, the annulus being angular in crosssectional form and having anannular rib or tongue running loosely in the groove of the rib on thespindle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

CHRISTIAN FOX.
